Rotating Shaft Locking Pliers for Versatile Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-clamp locking pliers require advanced preparation for different usage scenarios, leading to inefficiency and inconvenience.
Innovation Solution
A pair of locking pliers featuring a rotating shaft that can shift between two positions, allowing for two types of use, such as clamping a plate-like workpiece or inserting into an inclined hole, thereby enhancing versatility and reducing preparation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional locking pliers are designed for specific usage scenarios (plate-like workpiece or inclined hole), then the clamping function is optimized, but the device requires advanced preparation and cannot adapt to different usage requirements
Solution Approach 1:
The locking pliers incorporates a rotating shaft with a clamp member that can rotate between a first position (for clamping plate-like workpieces) and a second position (for inserting into inclined holes). This allows a single device to perform multiple functions that previously required different specialized tools, thereby improving adaptability without significantly increasing overall device complexity
Solution Approach 2:
The rotating shaft mechanism enables dynamic reconfiguration of the clamp member's orientation and position. The shaft can rotate to different angles and lock into positions, allowing the device to adapt its configuration based on the specific workpiece and clamping requirement, transforming a static single-function tool into a dynamic multi-function tool
2Productivity
If conventional locking pliers are designed for specific usage scenarios, then the clamping function is optimized, but time is lost due to need for advanced preparation
Solution Approach 1:
By integrating both clamping modes (plate clamping and inclined hole insertion) into a single device through the rotating shaft mechanism, users no longer need to prepare or switch between different specialized tools. The device can directly adapt to different workpiece types, eliminating preparation time and improving operational efficiency
Solution Approach 2:
The rotating shaft is designed with retention holes and retaining members that allow quick positioning and locking into predetermined angles. This preliminary configuration of possible positions enables the user to rapidly switch between functions without complex adjustment or preparation, reducing the time loss associated with function switching

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ability to shift between two types of use improves the versatility of the locking pliers, reducing the need for advanced preparation and resulting in cost savings and increased efficiency.
Implementation Method 1
The shaft body is rotatably connected with the fixed jaw about a pivot axis and is movable relative to the fixed jaw along the pivot axis
Implementation Method 2
The pivot member is operable to move along the pivot axis to bring the rotating shaft into movement close to or away from the fixed jaw
Implementation Method 3
The retaining member extends through the fixed jaw and the rotating shaft along a retaining axis that is parallel to and offset from the pivot axis so as to retain the rotating shaft to a selected one of the first and second positions

AI summary
A locking pliers includes a pliers-body, a rotating shaft and an operating and pivoting unit. The pliers-body includes a fixed jaw, a movable jaw and a jaw end member disposed on the movable jaw. The rotating shaft is rotatably connected with the fixed jaw about a pivot axis and is movable along the pivot axis, and has clamp and insert ends. A clamp member is disposed on the clamp end. A pivot member extends through the fixed jaw and connected with the rotating shaft and is operable to move the rotating shaft close to or away from the fixed jaw. A retaining member extends through the fixed jaw and the rotating shaft to retain the rotating shaft to a first or second position. With the rotating shaft rotated between first and second positions, the locking pliers can be shifted to two types of use.
